AUTOMOBILE-BRAKE.

Specification of Letters Patent.

Application mea october s, 190s. serial nu. 456,856.

To all 'whom it ma concern.' i

Be it known tiet I, RonmN "IL'W'm'rn, a citizen of the United States, residing at 'Cleveland in the county of Cuyahoga and a central horizontal section of the invention.4

Referring to the parts by letters A represents a non-rotative part having rigid with it two arms B, B which extend horizontally in opposite directions. 'lhepart A is intended to be secured to or formed on the outer end of what is sometimes known as the dead axle 7-tliat -is to say, the laterally extending tubular members of the casing which incloses the differential mechanism of a motor car.

C represents the hub of one of the driving wheels, which hub is rotatively mounted upon suitable anti-friction bearings in the outer end of the fixedl member A. An annular brake flange D is rigidly fixed to the wheel hub. The wheel hub itself is rigidly fixed to the live axle F .by any suitable means which will compel them to rotate in unison.

E' represents an inner brake ring which is, like all such brake rings, split through one side. At a point midway between'the split in this ring an inwardly projecting boss e is formed on'it in which is a horizontal slot e. fixed to the arm B, passes through this slot and supports the brake ring against rotation, but, obviously, permits a horizontal movement of the ring. Projecting-flanges at the ends of the bearing portion of stud pin b embrace the sides of boss e and pre- A flanged bearing stud 6.,'

vent lateral displacement of brake ring E. Adjustable bearing plates H are secured to the separated ends of this brake ring,-these plates being the heads of screws L which screw into said ends, and lie, when once screwed in, with their faces horizontal and parallel with each other. The screws h take into lugs L on the ends of the brake band, the lugs being split at one side of the screwI sockets as at k3 and provided with screws k2 across said split to draw their edges together and securely clalnp the screws L from turning away from' adjusted position.` A rock shaft K bearing an operating lever 7c' is mounted in the arm B and has between the plates H, H, a cam k which,

when the rock shaft is rocked in one direc.

tion, will, by bearing against the plates H, H, thrust the ends of the ring apart and so cause the entire ring to press against the inner periphery of the cylindrical flange D, the slot e permittingthe necessary horizontal movement of said ring to permit the entire engagement as specified. Projecting flanges at the ends of cam embrace the screw heads or bearing plates H, H between them and prevent lateral displacement of the ends of brake ring. A contractile coil springJ is stretched between and connected' with opposite arms of the split ring, and this spring exerts its force to draw the arms of the ring out of engagement with flange D when the cam has been turned to permitv this action.

It will be noted that in the foregoing con` struction the horizontal slot c, in the. brake ring permits it to move as required to free the adjacent parts/of said ring from contact with the flange D, or to permit it to come into contact therewith. The adjustableplates H furnish means for adjusting the brake ring E to compensate for wear.

Having thus described my invent-ion, .I claim:

The combination of a rotatable wheel having an annular brake flange, a non-rotatable member adjacent thereto and having a bearing stud mounted thereon, a floating Patented June 3. 1913.
